MACHINE FOR MORTISING WINDOW-STILES.

SPECIFICATION forming part of Letters Patent No. 552,301, dated December 31, 1895.

7 Application filed January 24, 1895. $erial No. 536,042. (No model.)

To all whom it may concern.-

Be it known that I, FRANCIS V. PHILLIPS, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Mortising VVindow-Stiles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention has reference to an improvement in gaging or guiding devices in machines for cutting pulley-mortises in windowframe stiles; and it consists in the matters hereinafter set forth, and pointed out in the appended claims.

The special improvement herein claimed relates to means for gaging or guiding the frame-stile by engagement thereof with the stop-groove in the stile, with reference to which groove the sash-pulley mortise must, of course, be cut.

Ileretofore in machines of this class the frame-stile has been guided from one or the other of its edges. In practice, however, it is found that the stop-groove is not accurately and uniformly related to the edges or to both edges of the stile, or, in other words, that the distance of the groove from the edge of the stile varies. To guide or gage the stile by the edge thereof is, therefore, calculated to bring the sash-pulley mortise out of place with reference to the stop which ultimately occupies the stop-groove to form a wall of the sash-groove of a window-frame.

This invention provides a gage which enters the stop-groove of a window-stile and determines the position of said stile in the machine accurately with reference to said stopgroove, and therefore with reference to the final sash-groove of the window-frame.

In the drawings illustrating my invention and accompanying this description, Figure 1 is a perspective of my improved mortising-machine or of so much thereof as is necessary to illustrate my present improvement. Fig. 2 is a detached view of one of the guiding or gaging devices of the machine for entering the stop-groove of the frame-stile. Fig. 8 is a vertical section in the line 3 3 of Fig. 1 of the main face plate of the machine, and show ing the adjustable supports for the gages seen in Fig. .1.

A represents the face-plate against which 5 5 the planed and grooved surface of a windowstile is placed and made to bear while the pulley-mortise is being cut by means of a suitable cutter protruding through the opening a in said face-plate.

B represents a clamp provided with a lever B by which the window-stile is held against the face-plate A While said stile is being op'- erated upon.

C C are two bars which both normally protrude beyond the surface of the plate A, but each of which is adapted to be retracted into a groove in said face-plate so that the outer surface of the bar will be flush with the working surface of said faceplate. Advancing 7o andretreating movement is allowed to each of the gage-bars C by providing thesaid bars with inwardly-turned ends 0, which are con fined loosely in grooves o in the holding-cap C, applied by means of bolts 0 to the end faces of the faceplate A, as clearly shown in Figs. 1 and 2. Suitable means are provided for giving to each of the bars 0 its normal protruding position, suchmeans being in the present instance shown in the form of springs c 0, connected with the bars C and bearing against the surfaces of suitable depressions in the faceplate. Each of the bars C is of proper width and size to enter a certain sized stop-groove in a window-frame stile, and the 8 5 bars C are desirably so mounted in the machine, as shown, that they may be replaced by others of different size adapted to fit the stop-grooves of different dimensions.

D represents a stop against which the end c of a window-frame stile may be pushed preparatory to operating upon the latter with the cutter. The window-stile, whether right or left handed, is placed against the face-plate A with its end against the stop D and with 5 its stop-groove occupied by the proper one of the gage-bars C, the other gage-bar being depressed by the ungrooved surface of the frame-stile when the latter is clamped to the face-plate A by means of the clamp 13. The foo groove of the right-hand stile will be engaged by one of the gage-bars C, and that of a lefthand stile by the other. Thus gaged and held the cutter makes the mortise in an accurate position with respect to the stop-groove.

As window-frame stiles of different sizes not only contain different sized stop-grooves but call for the placing of the gage-bars C C at different distances apart in the machine, the face-plate A is provided with a sufficiently wide depression a, to permit the gage-bars U C to be placed therein as far apart as maybe required, or moved as near to each other as may in other instances be necessary. gage-bars are then confined externally and suitably by the adjustable plates E E provided with slots for their holding-screws and movable vertically in grooves a of the faceplate, and intermediately by the spacingblocks E. s In shifting the gage-bars C O farther from or nearer to each other, the spacing-blocks E will be replaced. by others of proper length, while the slotted plates E E may be moved and reseeured intheir new positions.

Substitute guide-plates C, or their equivalents, will be employed in changes of the gage-bars.

I claim as my invention 1. I11 a window stile mortisin g machine, the combination, with a mortise cutter, of a face plate or rest and two separately retractible gages adapted severally to enter the stopgroove of a window stile and to gage the position of the stile in the machine by such engagenient of the gage therewith.

2. In a machine for cutting or operatin The upon a window stile having a stop-groove therein, a gage for the window stile, consisting of a long bar adapted to enter the stopgroove of the stile and also adapted to advance and retreat, and yielding means for holding the stop in its advanced position with respect to the surface of the face plate.

In a machine for cutting or operating upon a window frame stile having a stop groove therein, the combination of a face plate or rest, two separately retraetible but normally protruding gages consisting each of a long bar and each adapted to enter the groove of the window stile, and mechanism arranged to normally project said bars but permitting them to be independently depressed flush with the surface of the face plate or rest by the window stile when its stopgroove is engaged by the other of said bars.

4:. In a window frame stile cutting machine, a face plate provided with a wide groove or depression in its working face, in combinati on with two retraetible, but normally protruding, parallel gage bars of less width than said wide groove, and means :for securing said bars within the broad groove at varying distances apart, for the purposes set forth.

In testimony that I claim the foregoing as my invention I affix. m ysignature in presence of two witnesses.
